ANCHORAGE, Alaska (AP) — A paper published Wednesday says polar bears forced onto land because of melting ice are unlikely to find enough food to replace their diet of seals.

U.S. Geological Survey research biologist Karyn Rode (ROHD) says only small numbers of polar bears are using food found on land and may burn more calories foraging than they take in eating berries, eggs or birds.
